An aerofoil structure (1) comprising at least two spars (2, 4) spaced apart in a fore and aft direction so as to define a fuel carrying volume between the spars, and at least one longitudinal corrugated reinforcing member (6, 7) disposed between the spars, each reinforcing member being corrugated in the longitudinal direction to form a series of forward ridges (9) on a forward side of the reinforcing member and a series of aft ridges (8) on an aft side of the reinforcing member, wherein each reinforcing member is directly attached by its forward ridges to one of the spars or to the aft ridges of an adjacent one of the reinforcing members, and wherein each reinforcing member is directly attached by its aft ridges to one of the spars or to the forward ridges of an adjacent one of the reinforcing members. Also, a method of manufacturing an aerofoil structure. The reinforcing member(s) may extend substantially the entire length of the structure to reduce the number of manufactured parts of the structure, increase the stiffness of the structure and reduce the weight of the structure.
Structure portante (1) comprenant au moins deux longerons (2, 4) espacés dans les directions avant et arrière de manière à former un volume destiné à recevoir du carburant, et au moins un élément de renfort ondulé (6, 7) disposé entre les longerons, chaque élément de renfort étant plissé dans le sens longitudinal pour former une série d'arêtes avant (9) sur sa face avant et d'arêtes arrière (8) sur sa face arrière. Chaque élément de renfort est fixé directement par ses arêtes avant à l'un des longerons ou aux arêtes arrière d'un élément de support adjacent, de même que chaque élément de renfort est fixé directement par ses arêtes arrière à l'un des longerons ou aux arêtes avant d'un élément de renfort adjacent. Est également décrit un procédé de fabrication d'une structure portante. Le ou les éléments de renfort peuvent courir sensiblement sur toute la longueur de la structure, ce qui permet de réduire le nombre des pièces de cette structure, de raidir cette dernière et d'en réduire le poids.
